kernel: DoS of Intel Ethernet controllers after a period of IPv6 fragment flood

A Denial of Service in Intel Ethernet Controller's X710/XL710 with Non-Volatile Memory Images before version 5.05 allows a remote attacker to stop the controller from processing network traffic working under certain network use conditions.

In the IMM2 firmware of Lenovo System x servers, remote commands issued by LXCA or other utilities may be captured in the First Failure Data Capture (FFDC) service log if the service log is generated when that remote command is running. Captured command data may contain clear text login information. Authorized users that can capture and export FFDC service log data may have access to these remote commands.
